On Monday, one of her co-workers told her about the Cleveland rescue in an attempt to cheer her up.

“The biggest thing with me is people approach me as though my sister is alive. I know she isn’t. It’s upsetting to me,” Lara told HuffPost Crime. “I’m happy [the rescue] gives people hope or they think that it gives me hope, but it’s really hard on me. I know in my heart what happened.”

Lara said she hasn’t given up finding her sister — but she expects to find her sister’s remains.

Grissim was 16 when she disappeared after school in Vancouver, Wash. Her purse, ID and possessions were found May, 1972 in the woods northeast of Vancouver, near where other homicide victims had been found.

Lia Howard — whose 14-year-old nephew, Dylan Redwine, went missing in Colorado on Nov. 12, 2012 — says the Cleveland case has rejuvenated her family in its quest to find her nephew.

“It shows that missing children can be found even years later,” she said Tuesday in a phone interview. “When you don’t know where somebody is you put his name out there, because you never know where that someone is.”

The National Center for Missing and Exploited Children also released a statement of hope, noting that recoveries of missing children are growing:

NCMEC has seen a growing number of recoveries of long-term missing children. Every story we hear offers hope to the families who are still searching, that their own children will one day come home.

On May 7, the NCMEC is celebrating this important message of hope by honoring Jaycee Dugard and her family at the 2013 Hope Awards. They were reunited in 2009 after Jaycee was abducted 18 years before.

This story like those of Elizabeth Smart, recovered after 9 months; Shawn Hornbeck, recovered after 4 years; Carlina White, recovered after 23 years; and Steve Carter, recovered after 34 years is the reason why we never forget any missing child.
